i Application filed hpril 9, 1903. Serial lloL151i'7i5. (No model.)

Be itknown that'I, WALTER COLE, a citizen of the UnitedStatesrresidingin the city and county of San Francisco, State of California, haveinvented certain new and useful Improvements in Excavating Mechanism;and

- I do hereby declare the following to be a full,

- gating-ditches, or for the displacement of soil for the purpose'oftransporting the same to make a fill of hollow land.

To comprehend the invention, reference should be had to the accompanyingsheets of drawings, wherein Figure 1 is a perspective View illustratingthe mechanism as being used in'connection with the removal of soil froma newly-excavated irrigating-ditch; and Fig. 2 is side view of the saidmechanism, partly broken, the

same being viewed from'one end of the-irri gating-ditch.

In the construction of irrigating-ditches with the form of mechanism setforth and described in the application, Serial No. 146,947,

filed by me in the United States Patent Office.

on the 9th day of March, 1903, a central ridge 1 of dirt is left withinthe excavated ditch 2. This ridge'gives an uneven or unfinishedbottom'to the ditch. For the purpose of the present application theinvention is illustrated in the drawings as operating to remove suchridge 1 or the material left by the excavating-machine. 7

To the bank or side wall 3 of the ditch the supporting posts or uprights4 4: are placed, the distance between the posts being approxi matelyseventy-five feet. Through these supports or uprights extend the trackor cable 5, the ends of which are suitably held in place by beingattached to the anchors 5. This track, which is parallel with the ditch,may be suspended any desired height above the embankment 3, the samedepending solely upon the height of the supports or uprights 44.

To the suspended track or cable 5 is secured the block 6, which block isslidable upon the said track or cable toward or from the end supports oruprights/1 4. From this block upwardly extend the side pieces 6,

: which are united by the cross-piece 7. From this cross-piece thepulleys 7 are suspended, through which work 'the haulage-cables 8. Theslide-block 6, with its side pieces 6 and cross-piece 7, constitute ahoist-head slidably secured to the track or cable 5. This hoisthead islocked or clamped to the track or ca ble 5 by means of the screw-clamps8. These screw-clamps are of usual construction and The haulagesite tothat at which the suspended track or cable is located. The free end ofthe haulage-cables are attached. to studs 10, laterally extending fromthe side walls of the bucket or scuppet-10'. To give stability to thehoisthead, the same is held against inward turning by means of theanchor-cables 11.

The scuppet or bucket is held against the earth to be removed by aworkman within the trench bearing upon the handle 12. When commencingthe work of removing the soil, the scuppet or bucket is at that side ofthe trench or ditch where the hoist-engine 9 is situated. As thehaulage-cables 8 are wound upon the engine drum 9 the scuppet or bucket10 is drawn crosswise of the ditch or trench, so as to scoop the soiltherein in a manner similar to an ordinary scraper. During the movementof the scuppet or bucket 10 toward the side wall 3 the same filled withdirt is gradually raised orelevated until its upper surface bears firmlyagainst the hoisthcad, when the strain of the haulage-cable causes thescuppet or, bucket to gradually tilt or swing over to dump its load ontothe embankment 3, Fig. 2 of the drawings. To return the scuppet orbucket to itsposition after its load has been emptied, a return-cable 12is employed. This cable is attached to the back wall of the scuppet orbucket, running through pulley 13, snatch block 13, and pulley let. Thefree end of the cable winds upon the gipsy 14 of the engine 9. Duringthe forward or operating movement of the scuppet or bucket 10 by thewinding of the haulage'cables the cable 12 unwinds from the gipsy let,while during the return of the scuppet or bucket 10 due to the windingup of the cable 12 the haulage-cables unwind from the drum 9. After theproper removal of the soil in a line of out has been made the hoist-headis adjusted upon the suspended track or cable 5, so as to present a newline of cut to the action of the scuppet or bucket, the position of theengine being altered to conform to the changed position of thehoisthead. By reason of the anchor-cables 11 the hoist-head is held inposition to resist the pulling strain of the haulage-cables.

In case of the removal of dirt to fill in a hollow or low land thescuppet or bucket after being filled is at once returned to be emptiedtoward the position at which the engine is located.

Having thus described the invention, what is claimed as new, and desiredto be protected by Letters Patent, is

1. In an apparatus for removing soil, the combination with a suspendedtrackway, of a hoist-head adjustably secured thereto, haulage-cablesworking therethrough, a scuppet or bucket attached to one end of thecables, an engine for operating the haulage-cables, and means forreturning the scuppet or bucket toits starting-point without beingdisconnected from the haulage-cables.

2. In an apparatus for removing soil, the combination with a suspendedtrackway, of a hoist-head adjustably secured thereto, haulage-cablesWorking therethrough, a scuppet or bucket attached to thehaulage-cables, and an engine for operating the haulage-cables.

3. In an apparatus for removing soil, the combination with a suspendedt-rackway, of a hoist-head adjustably secured thereto, haulage-cablesworking therethrough, a scuppet or bucket attached to thehaulage-cables, an engine for operating the haulage-cables, and a cableactuated by the engine for restoring the scuppet or bucket to itsstarting position.

4. In an apparatus for removing soil, the combination with a suspendedtrackway, of a hoist-head adjustably secured thereto, haulage-cablesworkingtherethrough, a scuppet or bucket attached to the haulage-cables,an engine for operating the hanlage'cables, means for holding thehoist-head against displacement during the pulling strain of thehaulage-cables, and means for returning the souppet or bucket to itsstarting-point without being disconnected from the haulage cables.

In witness whereof I have hereunto set my hand.
